Interesting Early Science Fiction, but, the date is wrong (It's from 1937 not 1928)
This is a fascinating look at "the way the future was" according to people in the late 1930s (the date at the top identifying this film as being from 1928 is incorrect — all of the airplanes with swastikas on them being the first clue. IMDB identifies it as having been produced in 1937: https://www.imdb.com/title/tt0348366/).
It has that wonderful mix of dated technology, but with utterly earnest (and, for the time, scientifically accurate) depictions of how to travel from Earth into space. Moreover, the scale of the technology being shown is actually a bit closer to the reality of the Apollo missions than were the Flash Gordon/Buck Rogers notions of the American serials.
